Let's divide 662215 by 39
The aim is to understand the frequency of 39 in 662215.

On to step 1:
If we divide 6 by 39, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 39

On to step 2:
66 divided by 39 is 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 39 from 66 to get 27.
Include the next digit (2) from the dividend after 27, then repeat: 272 / 39

Moving on to step 3:
When dividing 272 by 39, we get 6 with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 234 from 272 to get 38.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 39

Step 4:
39 goes into 382 9 times with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
Deduct 351 from 382 and we're left with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 39

Going ahead to step 5:
39 goes into 311 7 times with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 1697.0
Subtract 273 from 311 to get 38.
Append the next digit (5) from the dividend to 38 and continue with: 385 / 39

Moving on to step 6:
385 divided by 39 is 9 with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 16979.0
Deduct 351 from 385 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
The number 39 fits into 340 8 times, leaving a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 16979.8
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
If we divide 280 by 39, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 16979.87
If we take 273 away from 280, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
39 can be fit into 70 1 times, resulting in a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 16979.871
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 10:
39 can be fit into 310 7 times, resulting in a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 16979.8717
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 11:
The number 39 fits into 370 9 times, leaving a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 16979.87179
If we take 351 away from 370, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
39 can be fit into 190 4 times, resulting in a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 16979.871794
If we take 156 away from 190, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
When dividing 340 by 39, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 16979.8717948
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
280 divided by 39 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 16979.87179487
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 16979.87179487 with a remainder of 7e-09.
